Processed Deli Meats
Processed meats like salami, hot dogs, bacon, and deli ham are loaded with sodium nitrates and preservatives that become increasingly dangerous after 40. Your body's ability to process these chemicals decreases with age, and studies show a 42% increased risk of heart disease in regular consumers over 40. These meats also contain high levels of sodium that raise blood pressure — a risk that compounds as your arteries naturally stiffen with age.
